If 5 or more beacons are placed in advance, then a machine is placed within their effect area, the machine can receive the effects of more than 5 beacons.

Beacon overload disables machines by script, regardless of them showing they're able to receive effects from more beacons.

Thank you for your reply.

After some additional testing, I believe the issue may be related to how the beacon limit is checked.

It appears that the beacon limit check does not iterate over all tiles occupied by the machine. Instead, it seems to sample only one or a few representative tiles within the machine's footprint.

As a result, if the sampled tile is within the range of only 4 beacons, the machine can still receive effects from 5 or more beacons without triggering the beacon limit.

This would explain why moving the machine by a single tile can change whether the limit is applied, even though the machine is still receiving effects from the same number of beacons.

Fixed for 1.3.36.
